Fwerk's turbo kit will get you there no problem. For a N/A car as you know theres no replacement for displacement= Get a 23 motor to start with= longer stroke for more grunt, the head flows a lot better. Add a set of cams, fwerk's header w/ Fwerk's stealth system, cossie intake or do a sheet metal intake, CFM's TB, of course a 91-93 octane tune w/ rear o2 senser & egr delete. For more mods= forged pistons/ rods/ ranger crank & SS 1 piece valve's. Add a Torsen & CFM's tubular control arm's to help get the power down.
Introduce Mr. Torsen to the mix
